Description
currently when no x-server is available (or other dbus errors) we just panic, but this could just be a warning and then continue without dbus.

To Reproduce

1. compile with dbus enables d
2. run without an x-server (i thing unsetting DISPLAY should also work).
3. run spotifyd normally
4. crashes with a panic

Expected behavior
a warning, but not a panic

This was #414 and we already declared victory on this. But this still interests me as the best option for enterprise hardening of Oragono: with native support for this, we could immediately reject any connection that doesn't have a valid certificate. (In a hypothetical enterprise setting, rapidly expiring certificates would then be distributed by a management agent.)

Not sure if this is the correct way to do it, but I wanted to save a cache script I could easily run.

"cache": {
      "desc": "Cache versions and update lock file",
      "cmd": "deno cache server.ts --lock-write",
      "lock": "./lock.json"
}

The result however when running denon cache is an endless loop instead of just executing it once, looks like this:

We avoid using cgo anywhere in the codebase since it causes problems with cross compilation. However, cgo would be advantageous in some cases (e.g. can use certain optimized libraries, can use libsecp256k1 bindings)

Investigate the viability of using xgo to do this. Test it on linux/osx/windows.
